I understand your point on the hub and sockets, but I haven’t seen them as a critical requirement for home automation. There are so many other devices that can be connected in other ways. Yes, they are required for some use cases, and it sounds like those use cases are most important to you. Sounds like hub 2.0 will upgrade the hardware and maybe it’ll be better for you. Or maybe not.
As far as engagement, I see them posting all the time and interacting with the community. Unfortunately, the answers aren’t always what people want to hear. In my development experience, it’s impossible to make the software that every one of your customers wants. You just try to do your best at prioritizing the work with the limitations you have.
